Argentina flyhalf Juan Martín Hernández will miss the Test against the Springboks in Mendoza as a result of a groin injury.

Hernández, who only recently returned from an injury-enforced three-season absence from Tests, suffered the injury during Wednesday’s training session. His loss is major blow for the Pumas, who rely heavily on his wide ranging attacking skill set.

Santiago Fernández, who was named at inside centre, is likely to shift into the position, although a call on this will only be made on Thursday.
